For this, JOpac2 is written in Java and is build on a class structure that make easy to load data in any ISO2709 format (ISIS, UNIMARC and text-only if you map it on a ISO2709 structure). JOpac2 is currently used by the University of Trieste for two small catalogs: non SBN data from a old ISIS based system and a journal catalog. Now at v.1.0, we are working for a new release and a loan module."

The ISIS2MARC can be used by other library software which is MARC compatible. polGenSQL has been modified. Its function allows the librarian to convert MARC data to sql commands compatible to PhpMyLibrary database structure."

Finally, we share with you what we have learned in this process and how our new knowledge affected creation of new requirements, as well as our future plans."
Not sure how we've missed this until now, but OpenIsis appears to be a format-compatible free-as-in-speech toolkit for working with Isis data.
Robert writes in: "There is rather good support for basic ISIS software (unfortunately they seem to be moving towards MS Windows) but it is very difficult to get free software (also free of charge) for constructing CGI. So I wrote my free iAPI (in C) to help others deal with problems I had before with ISIS." it's licensed under the GNU GPL...
I've now seen CDS/ISIS and its variants mentioned in several places and am still confused about what it is but here's a brief description nonetheless. from the UNESCO ISIS page: Micro CDS/ISIS is an advanced non-numerical information storage and retrieval software developed by UNESCO since 1985 to satisfy the need expressed by many institutions, especially in developing countries, to be able to streamline their information processing activities by using modern (and relatively inexpensive) technologies. The software was originally based on the Mainframe version of CDS/ISIS, started in the late '60s, thus taking advantage of several years of experience acquired in database management software development." take 2, from the CDS-ISIS user forum site: "Mini/Micro CDS/ISIS is a text retrieval program, designed and distributed free of charge by UNESCO. It is widely used for bibliographic (and other) databases throughout the world, and especially in developing countries." If I understand all this properly, it is basically a non-relational database environment commonly used by libraries and other largely nonprofits (20,000+ of 'em) throughout the world. I pulled down the unix version but can't quite make heads or tails of it. Somebody please explain more... update: collected comments from all who offered are available here.
